Lucapa Diamond Company recovered an “exceptional” 63.05-carat, Type IIa diamond from its alluvial mining operations at the Lulo Diamond Concession in Angola. It is the biggest diamond recovered since Lucapa started commercial mining operations at the site in January and the company’s third-largest stone unearthed at Lulo, behind 131.40-carat and 95.45-carat stones (both of which also were Type IIa).
